Types of Chromosomes

Q. A chromosome with a very long arm and a very short arm is termed as

1. Telocentric
2. Acrocentric
3. Metacentric
4. Sub-Metacentric

Q. Minimum coiling in chromosome is at
(a) prophase
(b) metaphase
(c) anaphase
(d) telophase

Q. ________ chromosome has centromere near the tip.

1. Acrocentric
2. Metacentric
3. Telocentric
4. Sub-metacentric

Q. In the metacentric chromosomes

1. Centromere is located at one end and has one arm
2. Centromeres are non-centrally located so that one arm is longer than the other
3. Centromeres are located in the centre two arms of the chromosomes are equal.
4. centromeres are found at the end so that one arm is very short and the other arm is long

Q. In the chromosomes, centromere is centrally located so that the two arms are of equal length.

1. telocentric
2. acrocentric
3. metacentric
4. submetacentric

Q.
